The First Lady reportedly invited Cleopatra Cowley-Pendleton and her 10-year-old son Nathaniel to the White House event, just one of many events the family has attended since the January slaying of their beloved 15-year-old daughter just one week after she performed at events for President Obama's second inauguration.

The crowd of more than 35,000 guests will gather Monday on the South Lawn for games, stories and of course the egg roll.

The event will feature celebs like Jordin Sparks, Coco Jones, Austin Mahone and special guest Robby Movak, also known as Kid President.

With the theme “Be Healthy, Be Active, Be You!” the event will also feature a string of celebrity athletes from across the country, including NASCAR’s Danica Patrick, Minnesota Viking Adrian Peterson and Olympians and Paralympians.

The event will live stream online for those who weren’t able to purchase tickets.
